The conservationist, 21, married fiancé Chandler Powell at Australia Zoo in Queensland on Wednesday, March 25, hours before the Australian government enforced a lockdown amid the coronavirus pandemic. The couple had originally planned to marry in a larger celebration on April 4.

“Remembering @RobertIrwin’s first wedding,” Terri captioned a throwback photo on Friday, March 27, showing the Crocodile Hunter, who died in 2006, holding the couple’s son, Robert. “I love that Steve and Robert both wore khaki. I know Steve would have worn khaki to Bindi & Chandler’s wedding, too. I wish he could have been there to see the most special day in his daughter’s life. We miss him so much.”

Bindi shared the post on Instagram and wrote, “Mum and Robert’s support has meant the world to me and Chandler during this special time in our lives. I had to share with you some of their kind words.
